I think they said it carries 1.1 million vehicles a day.

EDIT: here's the report - http://www.francetvinfo.fr/environne...in_484472.html

Yes, that's the figure that has been floated before.

That is the amount of vehicles using any part of the BP. These are not actual traffic counts. The AADT is expressed in the number of vehicles per day between two entry/exit points. Otherwise the numbers get distorted by road length. Toll road volumes are often distorted that way, because they count the number of transactions per road.

That's what I figured they meant. I'm still surprised by that low average speed, though. A hypothetical two rush hours a day during which no one was moving at all would still not offset doing 80 the rest of the day enough to bring the average speed down to 37, assuming each rush "hour" is really about three hours long. Or is that the average speed any given person enjoys (as opposed to the average of speeds at various times of day), so that if most people are traveling at rush hour....? You see what I mean. Thinking out loud here.

I guess average speed is measured calculating the speed of every vehicle through a certain point, so the low value is explained by the very high amount of vehicles driving through that point at a very low speed in rush hours.

A new alignment of N13 near Loucelles opened to traffic today. This means all of N13 between Caen and Bayeux is now a 2x2 voie expresse.

Yes and no - yes because they are one-way, no because you can use them for the other direction running the whole loop, like a giant roundabout. The A557 is purely one way.

It's basically a long sliproad. Its biggest special feature is having an own number. It's also very substandard for a motorway, too; there's a 50 km/h speed limit all the way from A7 to A55 (Marsellais drive 100 though).

Route du Littoral, Réunion

Launch of the Nouvelle Route du Littoral coastal highway on Reunion Island, including France's longest offshore viaduct

Jean-Luc Marx, Prefect of La Réunion, and Didier Robert, President of the Réunion Region, are today officially launching construction of the new coastal highway to be built by a consortium made up of VINCI Construction subsidiaries VINCI Construction Grands Projets (lead company) and Dodin Campenon Bernard, Bouygues Construction subsidiary Bouygues Travaux Publics and Demathieu Bard.

The 5,400 metre offshore viaduct, France's longest, will connect Saint Denis (the administrative capital of La Réunion) with La Grande Chaloupe. This is a major part of the offshore coastal highway, two lanes of which will be dedicated to public and "soft" modes of transport (bus, pedestrian/bicycle) and which will replace the existing coastal road between Saint Denis and La Possession, which is exposed to falling rocks and flooding by swells and tropical storms.

Work on the €715 million viaduct will be completed in 2018. It will be built by means of a technical solution proposed by the consortium in which 95% of the structures will be prefabricated on land and then for the most part installed by sea.

This ought to be one of the most unusual highway projects in the World.

Because the existing link (on foothill near the cliffs) is often disrupted by swells or - worse - rockfalls.



Since is the outer slopes of a dormant volcano, the only way around involves cutting over a steep 2-lane road.

Wasn't a tunnel feasible/a technically easier solution?

I don't think so, if you look at a map: http://goo.gl/maps/CeAZE

If such a thing actually gets built I will pray Poseidon to destroy it.

Since a tunnel is not viable and the current route is subject to lengthy suspension of services, what alternative do you suggest? A 10x more espensive highway going up and down the mountain inland?

If they are going to close every road in Italy just becaus of falling rocks hazard, there would be no roads open.

There are alternatives to "close the road and build another one".

Norway also replaces many rockslide-prone roads with tunnels, even with far lower AADT figures than Route du Littoral.
